SpaceX mission: Just the beginning

SpaceX made history Friday as the first private company to successfully reach an orbiting space station - but its competitors aren't far behind.

Blue Origin, the commercial space outfit founded by Amazon.com's Jeff Bezos, has been wind-tunnel testing its Space Vehicle capsule, which is designed to carry up to seven astronauts to the International Space Station, much like SpaceX's Dragon capsule.

Another company, Sierra Nevada, is preparing to dangle a test version of its shuttle-like Dream Catcher from helicopters later this year to find out how well it slips through the air. The sleek spacecraft - which could lift off as soon as 2016 or 2017 - is designed to launch atop a powerful Atlas V rocket and then use its wings to fly back to Earth for a runway landing.

And a fourth private firm called Orbital Sciences Corp. is planning its first launch later in the year.

SpaceX's achievement crosses an important threshold in America's shift toward a commercially led space industry. The door is opening to cheaper, more efficient and easier access to orbit, say experts, at a time when American astronauts must hitch rides aboard Russian spacecraft.

Blue Origin tested its capsule last month in Dallas, confirming its ability to descend correctly through the atmosphere and to change its flight path, according to a Blue Origin statement.

Blue Origin's New Shepard rocket system is designed for vertical takeoff and landing. The spacecraft's liquid oxygen-liquid hydrogen rocket engine systems have been undergoing testing at NASA's Stennis Space Center in Mississippi, the company said.

It's been in business for only 12 years, and the company is already creating museum pieces - in this case an unmanned test vehicle called Charon.

Workers in Seattle moved the 9,500-pound machine into the Museum of Flight on Tuesday. Charon and its four powerful vertically set jet engines helped New Shepard engineers learn more about reusable booster rockets that blast off and land vertically.

"We've all seen cartoons of rockets landing vertically, and it really hasn't happened yet," museum President Douglas King said. "Figuring out how to do that in a way that's controllable and replicable is what this is all about."

Flying Charon by remote control "felt like trying to balance something on top of  a ball," King was told. "That's what Blue Origin is trying to learn to do: to fly a rocket booster back to the pad and then land it gently."

Sitting in the museum's Space Gallery, about 20 feet to the right of Charon, is a Russian Soyuz rocket capsule that flew to the space station in 2009.

"You think about this little tiny capsule as being all that returned from a big three-part spacecraft, and you get an idea how expensive spaceflight is and how we need to make access to space reasonable for a lot more people," King said. "You've got to make it reliable and affordable to do that."

The Dragon mission is beginning to demonstrate the exciting moment in history we're living in, he said.

"Things that used to only be accessible to a few carefully selected highly qualified right-stuff government employees are finally coming within reach of researchers, businesspeople and explorers," King said. "SpaceX deserves a lot of credit. That's an incredible achievement out there today - done only by governments before - and a lot of other people are going to follow."

Launch success for SpaceX mission

California's SpaceX has launched on a mission to re-supply the space station - the first cargo delivery to the orbiting outpost by a private company.

The firm's Falcon rocket, topped by an unmanned Dragon freight capsule, lifted clear of its Florida pad at 03:44 EDT (07:44 GMT; 08:44 BST).

The initial climb to an altitude some 340km above the Earth lasted a little under 10 minutes.

Within moments of being ejected, Dragon opened its solar panels.

It also unpacked its navigation equipment.

It will take a couple of days to reach the station. The plan currently is for the vessel to demonstrate its guidance, control and communications systems on Thursday, at a distance of 2.5km from the International Space Station (ISS).

If those practice proximity manoeuvres go well, Dragon will be allowed to drive to within 10m of the station on Friday. Astronauts inside the platform will then grab the ship with a robotic arm and berth it to the 400km-high structure.

They will empty Dragon of its 500kg of food, water and equipment, before releasing it for a return to Earth at the end of the month.

For Elon Musk, the CEO and chief designer at SpaceX, Tuesday's lift-off was a special moment.

"Every bit of adrenalin in my body released at that point," he told reporters. "There's so much hope riding on that rocket, so when it worked, and Dragon worked and the solar arrays deployed, [company employees] saw their handiwork in space and operating as it should - it was tremendous elation. It's like winning the Superbowl."

The mission has major significance because it marks a big change in the way the US wants to conduct its space operations.

Nasa is attempting to offload routine human spaceflight operations in low-Earth orbit to commercial industry in a way similar to how some large organisations contract out their IT or payroll.

The carriage of freight will be the first service to be bought in from external suppliers; the transport of astronauts to and from the station will be the second, later this decade.

The US space agency hopes these changes will save it money that can then be invested in exploration missions far beyond Earth, at destinations such as asteroids and Mars.

"Although there's a lot ahead to complete this mission, we're certainly off to a good start," Charles Bolden, the Nasa administrator, told reporters.

"It's a great day for America… It's actually a great day for the world. There are people who thought we'd gone away, and today says we've not gone away at all," he said, alluding to the retirement of the agency's space shuttles last year.

SpaceX has many new systems it has to demonstrate in the coming days, and has tried to lower expectations ahead of the mission, repeating often that its aim is to learn things it did not previously know.

Nasa has set the California company a series of development milestones. Only when those have been met fully will a $1.6bn ISS re-supply contract kick in.

The agency is also looking to engage a second cargo partner. Orbital Sciences Corporation of Virginia is slightly behind SpaceX in its development schedule, although it started work on its Antares rocket and Cygnus capsule system later. Orbital expects to fly a first mission to the vicinity of the ISS later this year or early in 2013.

"We're really at the dawn of a new era in space exploration, and one where there's a much bigger role for commercial space companies," Mr Musk said.

"I think perhaps there's some parallels to the internet in the mid-90s where the internet was created as a government endeavour but then the introduction of commercial companies really accelerated the growth of the internet."

Tuesday's Falcon launch was also notable for the small and rather unusual payload that piggy-backed the ride to orbit.

This was a container holding the cremated remains of more than 300 space enthusiasts, among them the late Star Trek actor James "Scotty" Doohan.

The ashes had been placed in the Falcon's discarded second stage.

They will continue to circle the planet for about a year before falling back to Earth and vaporizing.
